1 Corinthians 7:2-4

7:2 But because of immoralities, each man should have relations with his own wife and each woman with her own husband. 7:3 A husband should give to his wife her sexual rights, and likewise a wife to her husband. 7:4 It is not the wife who has the rights to her own body, but the husband. In the same way, it is not the husband who has the rights to his own body, but the wife.

1 Corinthians 7:10

7:10 To the married I give this command – not I, but the Lord – a wife should not divorce a husband
